The recent invention of powerful precision tools for editing the human genome - known as CRISPR, has opened up new worlds of possibilities for researchers seeking to understand how our genes work - and also those who want to permanently change the human genome for generations to come. But are we on the road to designer babies? Plus, we unpack the latest cancer breakthrough, and our gene of the month is making a terrible racket. This is the Naked Genetics podcast for March 2016 with me, Dr Kat Arney, brought to you in association with The Genetics Society, online at genetics.org.uk.Listen to this Showor If you want to discuss this show, or ask a question, this is the place to do it.

Hi! I loved listening to this episode. I'm new to your podcast and the website and I am really enjoying all the information you provide! I have a question regarding the cancer research portion of this episode: what is holding the immune system back? You mentioned that some immune cells were found that went after the cancer antigens, and that one of the therapies would be to take the brakes off the immune system. What is it that's holding it back? I'm looking forward to your answer. Thank you!
